可以在cmd中输入nvidia-smi，但是通常情况下直接在cmd中输入nvidia-smi是没有用的，那该怎么办呢 找路...
在PyTorch中,max_split_size_mb 是PYTORCH_CUDA_ALLOC_CONF 环境变量中的一个重要参数,用于控制CUDA内存分配器可以拆分的最大内存块大小(以MB为单位)。这个参数的设置对于解决因显存碎片化导致的“CUDA out of memory”错误非常关键。以下是对max_split_size_mb参数的详细解释及设置方法: 1. 理解max_split_size_...
这个错误表示CUDA显存不足,尝试分配了1.88 GiB的内存但无法满足。已经有9.41 GiB的内存被占用,剩余786.00 MiB可用。 解决方法: 减少模型输入数据的大小或者减少batch size。 尝试调整PyTorch中GPU内存分配策略,可以在代码开头加入以下语句进行设置: importtorch ...
So having a reliable tool that pytorch counter is the only way to move forward, except more than one is needed. And as this feature requests we need multiple counters, since different gpu memory profiling tools measure memory peak usage at a different levels concurrently - program level, ...

2.batch size就是利用pytorch的dataloader来批量给数据,如果就想一次性给入全部数据的话,此方法不好用。 dataloader学习推荐莫烦的pytorch那一块的教程,巨清晰易懂 3.torch.cuda.empty_cache()这个代码是用来释放GPU reserved memory显存的,如果调用完函数之后,有的tensor并不会被释放,用这个。这个对我来说有用,但...
